Army Ant
The name army ant (or legionary ant or ''marabunta'') is applied to over 200 ant species in different lineages. Because of their aggressive predatory foraging groups, known as "raids", a huge number of ants forage simultaneously over a limited area. Another shared feature is that, unlike most ant species, army ants do not construct permanent nests; an army ant colony moves almost incessantly over the time it exists. All species are members of the true ant family, Formicidae, but several groups have independently evolved the same basic behavioural and ecological syndrome. This syndrome is often referred to as "legionary behaviour", and may be an example of convergent evolution. Most New World army ants belong to the genera '' Cheliomyrmex'', '' Neivamyrmex'', ''Nomamyrmex'', ''Labidus'', and '' Eciton''. The largest genus is ''Neivamyrmex'', which contains more than 120 species; the most predominant species is '' Eciton burchellii''; its common name "army ant" is considered ...

Sinharaja Rain Forest
Sinharaja Forest Reserve is a forest reserve and a biodiversity hotspot in Sri Lanka. It is of international significance and has been designated a Biosphere Reserve and World Heritage Site by UNESCO. According to International Union for Conservation of Nature (IUCN), Sinharaja is the country's last viable area of primary tropical rainforest. More than 60% of the trees are endemic and many of them are considered rare. 50% of Sri Lankan's endemics species of animals (especially butterfly, amphibians, birds, snakes and fish species). It is home to 95% endemic birds. The hilly virgin rainforest, part of the Sri Lanka lowland rain forests ecoregion, was saved from the worst of commercial logging by its inaccessibility, and was designated a World Biosphere Reserve in 1978 and a World Heritage Site in 1988. Because of the dense vegetation, wildlife is not as easily seen as at dry-zone national parks such as Yala. There are about 3 elephants, and 15 or so leopards. The most common lar ...

Sri Lanka
Sri Lanka (, ; si, ශ්රී ලංකා, Śrī Laṅkā, translit-std=ISO (); ta, இலங்கை, Ilaṅkai, translit-std=ISO ()), formerly known as Ceylon and officially the Democratic Socialist Republic of Sri Lanka, is an island country in South Asia. It lies in the Indian Ocean, southwest of the Bay of Bengal, and southeast of the Arabian Sea; it is separated from the Indian subcontinent by the Gulf of Mannar and the Palk Strait. Sri Lanka shares a maritime border with India and Maldives. Sri Jayawardenepura Kotte is its legislative capital, and Colombo is its List of cities in Sri Lanka, largest city and financial centre. Sri Lanka has a population of around 22 million (2020) and is a multinational state, home to diverse cultures, languages, and ethnicities. The Sinhalese people, Sinhalese are the majority of the nation's population. The Tamils, who are a large minority group, have also played an influential role in the island's history.

Animal Diversity Web
Animal Diversity Web (ADW) is an online database that collects the natural history, classification, species characteristics, conservation biology, and distribution information on thousands of species of animals. The website includes thousands of photographs, hundreds of sound clips, and a virtual museum. Overview The ADW acts as an online encyclopedia, with each individual species account displaying basic information specific to that species. The website used a local, relational database written by staff and student contributors from the University of Michigan. Each species account includes geographic range, habitat, physical description, development, ecosystem roles, reproduction, life span, communication and perception, behavior, food habits, predation, and conservation status. The organization of the site reinforces past biology knowledge by providing sharp images and showing common phyla on the home page. The Animal Diversity Web has resources other than its d ...

Dorylinae
Dorylinae is an ant subfamily, with distributions in both the Old World and New World. Brady ''et al.'' (2014) synonymized the previous dorylomorph subfamilies (Aenictinae, Aenictogitoninae, Cerapachyinae, Ecitoninae, and Leptanilloidinae) under Dorylinae., while Borowiec (2016) reviewed and revised the genera, resurrecting many genera which had previously been merged. Dorylinae genera are suggested to have evolved sometime between , subsequently undergoing rapid adaptive radiation events during their early history.

Hymenoptera Of Asia
Hymenoptera is a large order of insects, comprising the sawflies, wasps, bees, and ants. Over 150,000 living species of Hymenoptera have been described, in addition to over 2,000 extinct ones. Many of the species are parasitic. Females typically have a special ovipositor for inserting eggs into hosts or places that are otherwise inaccessible. This ovipositor is often modified into a stinger. The young develop through holometabolism (complete metamorphosis)—that is, they have a wormlike larval stage and an inactive pupal stage before they mature. Etymology The name Hymenoptera refers to the wings of the insects, but the original derivation is ambiguous. All references agree that the derivation involves the Ancient Greek πτερόν (''pteron'') for wing. The Ancient Greek ὑμήν (''hymen'') for membrane provides a plausible etymology for the term because species in this order have membranous wings. However, a key characteristic of this order is that the hindwings a ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
